You can use hold up switches in hospitals, banks, jewelry stores, retail establishments and any other location that has a need for hold up notification. (This means you can push a hidden button to silently notify the authorities of a robbery in progress.)
Why do I need the ADT Hold Up Button Reset Key?
You will not be able to use a hold up switch again and/or clear your alarm system if you do not reset your hold up switch. If you push your hold up button and you want to reset it, you will need to have this key.
